hi jano, i think i`ll probably go for the base map to be honest i`ve spent a lot of time and money to get all the webber bits on my car, cant see the point of taking them off. just want it running now so seems yhe easier and quicker option.

just one more thing. with the webber marrelli if i want say 20 odd psi max boost will the ecu automatically adjust fuelling etc if i lower it via my bleed valve via the map sensor.

cheers dude.
